I find the WT buzzwords to be fascinating. The one that bemuses me most is "fine". As in Jehovah's fine arrangement ("arrangement" is another buzzword that they seem to love peppering things with). Even to the point where Jesus is the "fine shepherd" (!) in their rendition of John 10:11 and 10:14! They can't even bring themselves to call Jesus "good"??
They started out differentiating between themselves and mainstream Christianity by rejecting standard terms, and having to find substitutes. So, information boards instead of bulletin boards, talks instead of sermons, all their different terms for office holders to not sound like they have a clergical hierarchy, Kingdom Hall instead of church and so on.
